Hello, When a user first starts the racket repl, it doesn't do line editing due to licensing issues. For example, it would be nice if the default editor would give the previous line if you hit up arrow, rather than writing "^[[A".
I have now pointed out xrepl to several users, and every time they always ask me why it's not the default repl. Apparently the problem is that xrepl uses GNU Readline, which is GPL. However, Asumu found that if we replace requiring readline with BSD's libedit (not libeditline), everything works fine due to libedit's readline compatibility. It doesn't have all of the features of readline, but it does have some of the biggest ones (such as being able to use arrow keys) What do you all think of having `(require editline)` that works for the default repl, so that it gets line editing features. This would allow us to also keep `(require readline)` as before, maintaining backwards compatibility. If we do do this, this leads to the question of distribution. Would we want to include libedit inside Racket distributions, or should we just link to whatever the user has on their system? ~Leif Andersen
